Abstract: A method and device are disclosed for industrial production of immobilized biocatalysts such as enzymes or microorganisms. In the method, a polyvinyl alcohol gel is produced containing the biocatalysts, and the gel is shaped in a stream of drying air. The device includes a continuous conveyor belt. A casting mechanism is positioned above the belt for applying a mixture containing a biocatalyst to the belt. Positioned for the belt to pass through following the casting mechanism, is a drying channel, a reswelling tank, a wiping and collecting device, a rinse box, and a drying channel.

Abstract: A method for the industrial production of the biocatalysts with biologically active material in the form of immobilized enzymes or microorganisms which are immobilized into the polyvinyl alcohol gel, and their use based on the fact, that the active biological material, formed by the mixture of free native or pretreated (aggregated) enzyme catalyst, or production microorganism, or part of them, and the polyvinyl alcohol gel, is used for their industrial production, the mixture is gelated and shaped in a stream of drying air at the temperature of 800 C to 150 C, considering the extent of the biologically active material, at the biocatalyst geometrical ratio of the surface to the volume kept larger than 7 mm‘l, and consequently thus prepared biocatalysts can be cultivated or stored and then use in biotechnological processes in the conditions, which ensure given biotechnological process higher productivity, higher production and enzymatic stability, long-term and repeated usage or definable process control with c
